Although Star Mining is a mess, his dormitory building is exactly what Jin San wants, and two large schools are enough to pull all the students in the surrounding three towns.

Originally, Jin San wanted to acquire Star Mining, and he went to those two large dormitory areas, but now it seems that Hou Zhong is planning to be even bigger!

"What's your kid's idea again?" Jin San couldn't help asking.

Hou Zhongdao: "Don't the big bosses have any ideas about the coal mine?" ”

Jin San said: "What can you think?" The coal seam is so deep that you still want to plant a diesel tree there and let it produce diesel for us? ”

"By the way, that's what I really think, big boss, you don't know this, although the cost of coal mining in the coal area is high now, it is because the coal seam below is too deep.

But it turns out that when coal mining began, there were a lot of coal seams left, especially old coal mines like Star Mining, because the technical level was very low when mining, so many shallow coal were left as top pillars, which can be used by diesel trees. ”

Jin San thought for a moment and said: "If this is the case, you can really make use of the coal there, a few hundred meters of coal seams can be used by diesel trees, but there is no way to go far, so, this is not of much use, you still stare at the dormitory building of Star Mining, don't have problems in this regard." ”

"No problem, just leave this aspect to me, you have time, study the diesel tree more, I think this thing has a future, if you can make his roots grow a few thousand meters, then he will really make a fortune, just absorb the coal in the ground and convert it all into diesel, then how much money does it have to have?"

Hou Zhong's eyes were misty, as if there were countless banknotes flying in front of him.

It doesn't seem impossible to let the root system of the plant grow thousands of meters, at least the bloodthirsty vine in Jin San's house is already thousands of meters long.

Although I don't know how long its root system is, just the speed at which it grows roots, I know that if the bloodthirsty vine needs it, its root system must grow very long.

After this period of accumulation, the task released by Jin San on the Jin family's water army online has been completed by several people, and all of them have been sent to him.

Although Jin San has to pay a minimum commission of 100,000 yuan for each mercenary who completes the task, he still thinks it is worth the money.

A fig tree in the Echo Cave near Faceless Oristad is estimated to be the deepest rooted plant in the world, with roots reaching 120 meters deep, equivalent to the height of a 40-story building above ground.

In addition to this mutated fig tree, there is an even more amazing plant, but it grows in the south of our country.

This is one of the most common plants, moso bamboo, which is the growth champion in the plant kingdom.

According to the relevant measurement data, under the condition of suitable climate, abundant water and sufficient fertilizer, the height of moso bamboo can grow day and night, which can reach about 1 meter 10.

Not only that, the growth of moso bamboo is also very tenacious, a broken bamboo shoot, even if it is pressed under a large stone of more than 100 catties, it will turn over the stone and rush to the sky.

A high-quality bamboo shoot bud planted in the soil, even in the most suitable climate environment, no matter how you water, fertilize, loosen the soil, this bamboo must be "silent" within three or four years, it is impossible to form a rapid growth trend.

Why is that?

And in such a long period of three or four years, what is Moso bamboo "doing"?

Relevant studies have shown that the reason why moso bamboo can grow more than one meter tall in one day, in addition to its own characteristics, the most important thing is to rely on the very large, developed and complex root system of moso bamboo.

The root system of the newly planted moso bamboo is very weak and underdeveloped, so the surface of the moso bamboo is heavy but not long, and it is alive but not growing.

Beneath the surface, the roots of the bamboo are growing desperately, stretching and spreading as far as possible.

It wasn't until the spring of four years later that the roots of the bamboo had grown layer after layer, intertwined and deep-rooted, and the total length of the root system gradually exceeded one thousand meters long.

With a rain, spring shoots broke through the ground, rose from the ground, and thrived.

If you want to grow quickly, you need to bury yourself deep in the soil to absorb nutrients and do your best to grow your root system.

For the first 5 years, it takes root for several kilometers in the ground, and it is almost impossible to see its growth.

When the sixth year of the rainy season arrives, it emerges from the ground and grows rapidly to a height of 30 meters at a rate of 60 centimeters per day.

Sixty centimeters tall every day, this is not the effect of Jin San's use of gene-boosting drugs, but naturally grown.

Such a strong vitality is all due to the gathering of that powerful root system.

It seems that this kind of moso bamboo will have to be carefully studied in the future, and if the diesel tree grows a root system of several thousand meters, it will really become a gas station.

Glancing at a bamboo plant in the corner of the wall, and a bag of bamboo seeds on the windowsill, Jin San still had a little headache.

Although this is a good thing, is it worth spending 100,000 yuan for such a bamboo plant and a bag of seeds?

Shook his head, don't care about it for now, since the school has been settled, now it's better to follow his father's instructions first, get some bronzes and sell them, to subsidize the family.

"Hou Zhong, don't dream, now it's better to help me buy some pure copper, preferably ore, and scrap copper." Jin San thought that he wanted to make something this time, and it was best to form a series with the Republic Ding and the Bronze Ban, then the only thing he was most familiar with was the wine vessel.

Why don't you do some Triangle Tiger Venerable or Four Sheep Fang Venerable?

With a wine case like the bronze ban, it is natural to have a wine jug to match, so he created a so-called Qi tomb for those who have a heart, imagine what is in a tomb, and since it has been done, he will make a full set.

"Big boss, you make money quickly, but you can spend money faster, you just got 19 million dollars and can't be moved, so where am I going to buy copper ore for you?

Besides, if you let everyone in the world know that you bought copper ore, aren't you telling people that the bronzes you made are fakes? Hou Zhong reminded Jin Sandao.

Jin Sanyi thought that this was really the case, even if his nineteen million dollars could be used, he could no longer blatantly buy copper ore.

"What then? How can I make copper without copper ore, and how can I make bronze without bronze? Jin San lamented.

Jin Sanyi rolled his eyes and said, "Big boss, do you think you can refine copper ore by yourself?" I see that among the tasks you posted, there is a grass that can smelt copper, let's plant some of that grass, and if you refine it, won't there be copper? ”

"Grass that can smelt copper? You're talking about copper grass? Jin San immediately remembered that there was a strange plant that was sent with the bamboo.

This plant is also very common, but it can absorb copper, so it is also a strange plant.

This task was completed, and the mercenary exchanged a few catties of copper grass seeds for 300,000 yuan, and Jin San also lost money in this transaction, but who let this copper grass meet his conditions!

There is a folk proverb about copper grass: "Toothbrush grass, purple flowers, where there is copper, there is it." ”

The copper grass will bloom beautiful flowers every autumn, the flowers are purple, gorgeous and dazzling, and the fragrance is fragrant.

According to the study, each kilogram of copper grass rhizome contains 1 gram of copper, which is about 1/3 of the same amount of ordinary copper ore.

Not only does it have a strong adsorption capacity, but it also has a fast growth rate, which is convenient for large-scale cultivation and harvesting, and is a good way for plants to improve copper-contaminated soil.

Copper grass is a plant that can absorb copper metal in the soil, and people say that "when you see copper grass, you have copper", which is the origin of the name copper grass.

This plant has a high copper content, is a sign of the search for copper ore, geologists in the wild, as long as they see this plant growing more in a certain place, will increase the workload, underground copper ore will be found.

This lush copper grass absorbs too much copper in the soil, and its roots, stems, leaves, and flowers can also be used to smelt copper, and if it is used as fertilizer, it can solve other problems of copper-deficient soil.

The copper content of one thousandth, such a content is neither high nor low, about 1/3 of the same amount of ordinary copper ore, if there is a large amount of copper grass, this is really a good way to smelt copper.

However, to grow this copper grass, you need to be in a place where there are copper mines.

In the vicinity of Jinjia, there are really copper mines, but the copper ore content in most places is not high, only the airfield west of Guhe Town is the main vein of copper mines, where the copper ore content is the highest and most concentrated.

However, there is an airstrip in that place, which cannot be mined, and in other places, although there are copper mines, there is no mining value, but it is enough to grow copper grass.

"How? Will it work? Hou Zhong asked.

Jin San reacted and said: "Okay, I'm going to do the experiment, if it really happens this time, not only will the problem of the copper mine be solved, but even the diesel tree with a root system of several kilometers that you just mentioned will also have it." ”

"Huh? A diesel tree with roots several kilometers long? Isn't it enough for a single tree to cover a small mine? Hou Zhong said in surprise.

Hou Zhong just talked about it, but even if he could imagine it, he just wanted the diesel tree to have a long root system of hundreds of meters.

That's it, just now Jin San said that he was dreaming!

Unexpectedly, in the blink of an eye, Jin San told him that the diesel tree with thousands of meters of roots was not a dream.

Jin San no longer paid attention to Hou Zhong, he directly entered the Tibetan Horse Valley, in this Tibetan Horse Valley, there is a hut, which is built by Jin Yuan, usually used for rest, Jin San occasionally has new ideas, and also does some experiments here.

It was because Jin San valued the secrecy of this place that he used this place as his temporary experimental base.

A lot of equipment in the greenhouse outside, Jin San asked people to get a copy and put it here, but now there is nothing to do experiments.

Jin San first studied the root system of moso bamboo, which is too developed.

Although it grows more slowly, this is not a problem, the question is how can it grow such a well-developed root system.

Just find out the gene strand that influences this factor, and you're good to go.
